From May, 1971 to June, 1984, we performed extensive saucerization on the chronic osteomyelitis of long bones eradicating all pathologic foci; not only sequestra but sclerotic involocurum and necrotic original cortex embeded by new bone, which was different from the conventional methods such as sequestrectomy or guttering in its extensiveness. Clinical analysis on the base of radiologic evaluation after saucerization was done on the 16 patients; for average 5 years of follow-up. The results obtained were as follows; 1. The angulatory deformity of the long bones after pathologic fracture complicated by the chronic osteomyelitis was not corrected satisfactorily due to the bony sclerosis or hyperostosis at the fracture site, especially in cases of posterior or medial angulation. 2. The recurrence was closely related to the persisting non-sequestered original cortical lesion after incomplete saucerization, which was embeded by the new bone. So to prevent the recurrence the non-sequestered original cortical lesion must be removed completely. 3. The cortical defect after saucerization was restored completely in patients under the age of 14, but which was not the way in patients over the age of 16.

Two cases of malignant histiocytosis, in which skin involvement was a prominent finding at initial clinical presentation, are reported. 1nteresting histopathologic findings, including Langerhans granule in one case and numerous eosinophils in another, were observed. In one case remission was achieved with BACOP chemotherapy (Bleomycin, Adriamycin, Cyclophosphamide, Vincristine, and Prednisone). In the other case, the patient died nine months after the onset of the disease without any treatment.

The aim of this study is to elucidate whether the beauty of Chosun dynasty was different from that of Japanese Edo dynasty or present Korea by anthropometric analysis. We analyzed faces of 6 portraits of beauty of Chosun dynasty and 5 of Japanese Edo dynasty, and 9 photographs of prize-winner in the beauty contest of Korea during resent 3 years. We measured the 20 anthropometric items on each portraits and calculated 17 proportional indices of the face. Portraits of beauty of Chosun dynasty had the greater value on 1 proportion index(ratio of nasal width to intercanthal distance) and less value on 3 proportion index(ratio of horzontal dimension of palpebral fissure to intercanthal distance, Ratio of height of vermilon to transverse width of mouth, eye fissure inclination) than Edo dynasty. Portraits of beauty of Chosun dynasty had the greater value on 1 proportion index(ratio of height of upper eyelid to total facial height) and less value on 3 proportion index(ration of vertical dimension of palpebral fissure to total facial height, ratio of nasal width to intercanthal distance, eye fissure inclination) than nine prize-winner of beauty contest of Korea. In conclusion, beauty of Chosun dynasty has lower eye fissure inclination, wider nasal ala, and thiner lip than one of Edo dynasty. Beauty of Chosun dynasty has oriental eyelid, wider upper eyelid, narrower eye fissure, lower eye fissure inclination, narrower nasal ala than present beauty.

Fracture dislocation or dislocation of the knee can produce a popliteal artery injury that may be difficult to evaluate clinically. Diagnosis of disruption or thrombosis of the popliteal artery is frequently delayed until the opportunity to salvage the extremity is lost. 22 cases of popliteal artery injury were reviewed from July 1978 to December 1983, associated with severe knee trauma at the Orthopaedic department of Kyung Hee University Hospital, of whom average follow-up for about 52 months. The results obtained were as follows; 1. In all 22 cases, 14 cases (63. 6%) were amputated. The amputation rate was correlated with ischemic time after injury. 2. Resection of all injuried vessels with reconstitution of continuity by the use of an interposed saphenous vein graft is often warrented to avoid tension. 3. All 8 patients, which was managed conservatively, were amputated in all cases(100%). In cases of suspicious popliteal artery injury, early aggressive exploration and obvious microvascular reconstruction should be mandatory. 4. Subperiosteal fibulectomy-fasciotomy should be done routinely immediately after vascular injury. 5. Diagnosis of popliteal artery injury was based on the clinical findings but the capillary filling was not contributary. 6. The use of Doppler flowmeter and emergency arteriography was recognizedtobeanexcellent methods in determination of arterial injury.

PURPOSE: To evaluate the usefulness of echo-planar FLAIR imaging in various cerebral lesions as compared with fast FLAIR imaging. MATERIALS AND METHODS: We obtained consecutive fast FLAIR and echo-planar FLAIR images in 33patients in whom MR imaging had revealed ischemic infarction (n=11), acute infarction (n=5), brain tumor (n=3), other conditions (n=3) or no abnormality (n=11). On both sets of images, percentage contrast and contrast to noise ratio (CNR) were calculated for white matter-gray matter and white matter-lesion. RESILTS: White matter-gray matter percentage contrast and CNR were lower on echo-planar FLAIR imaging than on fast FLAIR imaging (percentage contrast, 19 +/- 2 % vs 28 +/- 3 %, CNR, 2.77 +/- 0. 5 vs 4.86 +/- 0.7). White matter-lesion percentage contrast on echo-planar FLAIR imaging was similar to or greater than that on fast FLAIR imaging; 75 +/- 12 % vs 45 +/- 11 % in ischemic infarction, 80 +/- 12 % vs 78 +/- 11% in acute infarction, and 121 +/- 25 % vs 102 +/- 15 % for tumors. White matter-lesion CNR was similar on both sets of images: 8.3 +/- 0.9 vs 7.9 +/- 0.8 in ischemic infarction, 11 +/- 1.5 vs 9.5 +/- 1.2 in acute infarction, and 24 +/- 4 vs 27 +/- 3 for tumors. Due to high susceptibility to magnetization, echo-planar FLAIR imaging showed image degradation at the interface of the paranasal sinus and adjacent to the temporal bone. CONCLUSION: Echo-planar FLAIR imaging may be a useful pulse sequence in the diagnosis of various cerebral lesions.

BACKGROUND: For the treatment of Parkinson's disease, dopamine-producing cells or genes involved in producing dopamine or supporting neurons have been tested to replace conventional chemical therapies. Of these, tyrosine hydroxylase (TH) was the most widely used gene for the therapy. Trials using TH via various vectors yielded behavioral improvements in animal models but the effectiveness did not last long enough. As one of the approaches for solving this problem, the regulation of expression of the protein and mRNA of TH was studied. METHODS: Two approaches for a higher and/or more stable expression of TH were pursued. First, the effect of cofactor tetrahydrobiopterin (BH4) on the expression level of TH and second, the effect of deletion which enables TH protein to escape from protease attack, were examined. RESULTS: Cells producing BH4 showed an approximately 10-fold higher TH expression than cells expressing TH alone. When the in vitro modified TH was expressed in NIH-3T3, mutant THs showed elevated protein (17.5 ~68.6 fold) and mRNA (1.8 ~4.6 fold) expression levels at a steady state. CONCLUSIONS: Results suggest that an addition of BH4 has a more positive effect on mRNA expression levels than protein. However, the deletions seem to have a tremen-dous effect on the translation and/or protein stability, but a small effect on the mRNA level. (J Korean Neurol Assoc 19(5):514~519, 2001)

Systemic lupus erythematosus (SLE) which is thought to be autoimmune in nature affects multiple organs and produces a diversity of signs and symptoms. However, cardiovascular manifestations of SLE are manifested more frequently by autopsy. Recently, with the prolonged survival and improvement of diagnostic methods in SLE including echocardiography, the morbidity and mortality associated with cardiovascular manifestations of SLE became more apparent and increased. Simultaneous involvement of the pulmonary artery and the myopericardium in SLE is known to be rare. Pulmonary hypertension is known to be associated with poor prognosis. We report a 27 year-old female patient of SLE with pulmonary hypertension, pericarditis and left ventricular systolic dysfunction.

This study was performed to demonstrate the ultrasound, biomicroscopic and dimensional changes of angle structure after laser iridotomy (LI) and primary trabeculectomy (PT) in primary angle-closure glaucoma (PACG). Angle-opening distance at a point 500 (m from the scleral spur (AOD500), trabecular-iris angle (theta1), trabecular ciliary process distance (TCPD), ciliary process-iris angle (CPI), iris thickness (ID1, ID3), length of iris-lens contact distance (ILCD) and anterior chamber depth (ACD) were assessed before and after each procedure. Thirteen patients with LI and 16 with PT were prospectively enrolled. There were statistically significant increases in AOD500, theta1, and ILCD in both groups. CPI was decreased in both groups. ACD, TCPD, and iris thickness were not changed significantly. The changes in angle configuration after LI or PT may result more from alterations in aqueous pressure gradients across the iris and the changes of configuration were greater in the iris roots without rotation of ciliary body. However, we didn't find any significant differences in the changes of parameters between the two procedures.

PURPOSE: The aims of this study were as follow: 1) to de scribe the expression status of estrogen receptor-alpha and -beta mRNAs in five gastric carcinoma cell lines; 2) to evaluate in vitro the effects of 17beta-estradiol and estrogen receptor antagonists on the proliferation of the cell lines. MATERIALS AND METHODS: Detection of estrogen receptor-alpha and estrogen receptor-beta mRNA in five human gastric cancer cell lines (AGS, KATO III, MKN28, MKN45 and MKN74) was made by the reverse transcription-polymerase chain reaction system. To evaluate the effect of 17beta-estradiol and estrogen receptor antagonists on the proliferation of gastric cancer cell line, the cell lines which expressed both es trogen receptors were chosen and treated with 17beta-estradiol and estrogen receptor antagonists (methyl-piperidino-pyrazole and pyrazolo [1,5-a] pyrimidine). Cell proliferation was assessed with the methylthiazol tetrazolium test. RESULTS: Estrogen receptor-alpha and estrogen receptor-beta mRNAs were expressed in three (KATO III, MKN28 and MKN45) and all of the five gastric cancer cell lines, respectively. At higher concentrations, 17beta-estradiol inhibited cell growth of MKN28, MKN45 and KATO III cell lines. Neither estrogen receptor-alpha nor estrogen receptor-beta antagonist blocked the anti-proliferative effect of 17beta-estradiol. CONCLUSIONS: Our results indicate that estrogen receptor-beta mRNAs are preferentially expressed in gastric cancers and also imply that hormone therapy rather than estrogen receptor blockers may be a useful strategy for the treatment of estrogen receptor-beta positive gastric cancer. Its therapeutic significance in gastric cancer are, however, limited until more evidence of the roles of estrogen receptors in the gastric cancer are accumulated.
